I like to consider myself a fairly seasoned veteran when it comes to all things cinematically bad (I don’t call myself “Trash Film Guru” for nothing), but once in awhile something comes along that defies even my ground-down-over-time ability to adequately process. I’ve seen plenty of films that make no sense whatsoever — some good, some decidedly less so — but one thing even the most inexplicably bizarre servings of celluloid sewage have in common is that they were all trying to do something. Maybe it wasn’t something worth trying. Maybe it was something they flat-out shouldn’t have tried. But right or wrong, they all see it through to the end and sink or swim based on whatever fucking idea or premise they started out with.

Such is not the case with director John Hijiri’s 2009 zero-budget mega-turkey Jaws In Japan, which I caught earlier today streaming on Amazon Prime under its alternate international DVD (and whatever you do, I wouldn’t recommend sinking your hard-earned money into that) release title, Psycho Shark. This flick is like nothing I’ve ever seen simply because it seems to change its mind not once, but twice, about why it even exists. And as its thankfully brief 70-minute runtime drew to a close, all I could think is that it probably shouldn’t even exist at all.

Initially, Hijiri and screenwriter Yasutoshi Murakawa seem to be happy to simply dish out yet another Japanese bikini-romp, which makes sense given that its supposed “stars,” Nonami Takizawa and Airi Nakajima (as fun-loving college girls Miki and Mai, respectively) are what’s known as “gravure idols,” and neither of them can act worth a damn. Pretty early on, though, the decision is made that watching two admittedly quite pretty young ladies run around half-naked isn’t enough in and of itself to keep viewers interested if they’re not gonna get completely naked at some point, and so, while the “wear a swimsuit at all times” trope doesn’t go away, by any means, it’s simply steered into service of something that has the makings of an ostensible plot. Cue abrupt change number one.

This is the point at which our nubile co-eds find themselves completely lost on the island paradise they’re vacationing at and end up meeting a skeevy local who guides them to a hotel owned by a creep with blood under his fingernails who’s probably killing off tourists but, like an idiot, leaves their camcorders around for people like Miki and Mai to find. So, yeah, what we’re apparently looking at now is some sort of “found footage” serial killer flick. And a damn boring one at that.

Unless, of course, roughly 45 mish-mashed minutes of watching shit “shaky-cam” footage, watching girls watching shit shaky-cam footage, and watching those same girls sleep, go to the beach, and take bikini-clad showers sounds gripping to you. There’s honestly more attention paid to — and more dialogue focused on — those ever-present bikinis than there is to the “killer on the loose” storyline, which is fair enough given that bikinis are more interesting than said storyline, but seriously — why not just make a “gravure” feature and leave it at that?

Evidently, Hijiri and Murakawa decided their “mockumentary”-style movie-within-a-movie wasn’t working out too well, either, so with approximately ten minutes to go, they abandon that conceit in favor of abrupt change number two : a giant CGI shark. Earlier scenes in this film borrowed obviously (and ineptly) from both Psycho and The Ring, but seriously, even though the film’s title gives it away, the sudden and hard pull into Jaws territory makes no sense whatsoever and feels very much like the last-second addition that it is (which makes me wonder what they were gonna call it before tacking this shit on at the end, but whatever). If you’ve got whiplash at this point, rest assured, you’re not alone.

Or maybe you are, because chances are that nobody else is awake at this point. Seriously, unlike other rankly amateur cut-rate CGI abominations like Birdemic, there’s just nothing weird or interesting going on here to maintain your interest until that shark shows up at the end, and by then it’s all far too little, far too late. It seems really strange that a film with pretty young women running around in next to nothing capped at the end with a laughably absurd CG monster could be boring, but that’s exactly what Jaws in Japan is. In fact, it’s downright interminably dull. And while I can certainly forgive (heck, more often than not I love) ultra-low budgets, cheesy FX, and absurd stories, one thing I can’t forgive is dullness. And no matter how many times Hijiri tries for a “do-over” with this thing, he never figures out how to turn it into anything you’re going to give a shit about.
